The Ultimate Addons for Beaver Builder – Lite plugin for WordPress contains a stored cross-site scripting vulnerability (CWE-79) in its Image Separator widget due to improper neutralization of input during web page generation. This allows authenticated attackers with contributor or higher privileges to inject arbitrary JavaScript code that executes in the context of users viewing the compromised pages. The vulnerability affects all versions up to and including 1.5.7. The CVSS 3.1 score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, which execute in the browsers of users who visit those pages. This can lead to unauthorized actions performed on behalf of users, data theft, or session hijacking. The impact is limited to confidentiality and integrity with no direct availability impact. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or avoiding use of the Image Separator widget. Monitor for updates from Brainstormforce regarding patches or official mitigations.
